AK-1 does have active protection system imported from Ukraine and integrated in HIT and it is now a standard fit on AK-1 by the name of VARTA (guards). Other changes are...
Sagem Matis TI (3rd Gen)
Turret control all electric instead of semi-electric previously
Increased ammunition to 49 rounds (main gun)
new ballistic computer with new sensors
Second Generation IBMS (indigenous)
Indigenous ERA along with composite armor (750 mm turret thickness without ERA) more than 1100 mm with ERA
Main gun improved based on Ukrainian KBA 125 series previously, now completely modified and built in HIT facility with increased accuracy, barrel life and range.
Improved suspension with hydraulic assistance more than previous version.
Much higher automation and protection for crew, new NBC developed indigenously, tracks, thicker side skirts. Better cooling for crew comfort, also a new DU shell developed based on French and Korean shells with higher penetrations at POF.
Improved autoloader with electric control.
I would say its at least twice as lethal as the previous AK.
